I dont think you understand what i mean by the suppression due to using AAS. Yes test is recommended when cycling due to that suppression on cycle but that only solves the problem while on cycle. The problem is your body is still not producing any natural test for an extended period of time because it has no need to. Therefore you come off and you are still suppressed. This can lead to it never coming back. This is one of the reasons why it is not recommended at all at your age.
